Look deeper

Pulmonary arterial hypertension (PAH) is a rare condition, with non-specific symptoms like ‘breathlessness’.1 You have to look deeper to uncover it.
On average, it takes nearly 4 years from the first noticeable symptoms to a confirmed PAH diagnosis.2

PAH patients are given an average of 2 ‘alternative’ diagnoses before their condition is correctly identified.2

PAH is a highly comorbid and deadly disease, with a median survival that can be as low as 6 months in patients who don’t receive treatment in time.*3
*Functional class IV patients who don’t receive PAH-specific treatment.

Knowing the signs & symptoms of PAH could save your patient’s life

World Health Organization functional class (WHO-FC) for patients with PH3,5

This system grades PH severity according to the patient’s functional status, by linking symptoms with activity limitations. WHO-FC remains a powerful predictor of outcomes in patients with PAH.

WHO - FC Description
I
Patients with PH in whom there is no limitation of usual physical activity; ordinary physical activity does not cause increased dyspnoea, fatigue, chest pain, or presyncope.
II
Patients with PH who have mild limitation of physical activity. There is no discomfort at rest, but normal physical activity causes increased dyspnoea, fatigue, chest pain, or presyncope.
III
Patients with PH who have a marked limitation of physical activity. There is no discomfort at rest, but less than ordinary activity causes increased dyspnoea, fatigue, chest pain, or presyncope.
IV
Patients with PH who are unable to perform any physical activity at rest and who may have signs of right ventricular failure. Dyspnoea and/or fatigue may be present at rest, and symptoms are increased by almost any physical activity.
